Possible LED attachment improvements

I see that Digikey and mouser now list pure indium solder wire, not cheap but not terribly expensive either. $20 per 3m spool, if I calculate correctly that comes out at $1.8 per gram.
Still 50% more expensive than indium scraps from China but I have more trust in ChipQuick purity…and wire is a bit more convenient.

Thanks for the heads up! That's very practical at these prices.

Note that he CDC says to wash your hands after touching it and to not eat it. :)
